In my (very) humble opinion, the gear that you mention is all decent quality.
It depends on what sort of gigs you want to be playing. From my point of view, the basses sound fine - providing that you're comfortable with them. I would look at your amplification - possibly something in the 250/300 watts area, posdibly something like this:

or something of similar power.
Another route could be an amplifier head & separate cabs, again of similar wattage. I have mainly used an Ashdown MAG250 or Eden WT264 head with an Ashdown ABM-115 mini, and if I needed more, an added Trace Elliott 2103h cab.
If you like your basses, keep them.
I'm sure other more experienced Basschatistas (?) will be along shortly with their views.
